ARGUMENTS
One of the symbolic constants TK_ANCHOR_N, TK_ANCHOR_NE, etc. See Tk_GetAnchorFromObj(.TH 3tcl). A
rectangular region from which a parcel is allocated. Extra padding (in pixels) to add uniformly to each
side of a region. Extra padding (in pixels) to add to the bottom of a region. Specifies a rectangular
region. The height in pixels of a region. Used to store error messages. Extra padding (in pixels) to
add to the left side of a region. String value contains a symbolic name to be converted to an enumerated
value or bitmask. Internal rep may be be modified to cache corresponding value. Extra padding to add on
the inside of a region. A rectangular region, allocated from a cavity. One of the standard Tk relief
options (TK_RELIEF_RAISED, TK_RELIEF_SUNKEN, etc.). See Tk_GetReliefFromObj. Extra padding (in pixles)
to add to the right side of a region. One of TTK_SIDE_LEFT, TTK_SIDE_TOP, TTK_SIDE_RIGHT, or
TTK_SIDE_BOTTOM. A bitmask containing one or more of the bits TTK_STICK_W (west, or left), TTK_STICK_E
(east, or right, TTK_STICK_N (north, or top), and TTK_STICK_S (south, or bottom). TTK_FILL_X is defined
as a synonym for (TTK_STICK_W|TTK_STICK_E), TTK_FILL_Y is a synonym for (TTK_STICK_N|TTK_STICK_S), and
TTK_FILL_BOTH and TTK_STICK_ALL are synonyms for (TTK_FILL_X|TTK_FILL_Y). See also: grid(n). Window
whose screen geometry determines the conversion between absolute units and pixels. Extra padding at the
top of a region. The width in pixels of a region. X coordinate of upper-left corner of region. Y
coordinate of upper-left corner of region.
BOXES
The Ttk_Box structure represents a rectangular region of a window: typedef struct {
int x;
int y;
int width;
int height; } Ttk_Box; All coordinates are relative to the window.
Ttk_MakeBox is a convenience routine that contsructs a Ttk_Box structure representing a region width
pixels wide, height pixels tall, at the specified x, y coordinates.
Ttk_PadBox returns a new box located inside the specified parcel, shrunken according to the left, top,
right, and bottom margins specified by padding.
Ttk_ExpandBox is the inverse of Ttk_PadBox: it returns a new box surrounding the specified parcel,
expanded according to the left, top, right, and bottom margins specified by padding.
Ttk_PackBox allocates a parcel width by height pixels wide on the specified side of the cavity, and
shrinks the cavity accordingly.
Ttk_StickBox places a box with the requested width and height inside the parcel according to the sticky
bits.
Ttk_PlaceBox combines Ttk_PackBox and Ttk_StickBox: it allocates a parcel on the specified side of the
cavity, places a box of the requested size inside the parcel according to sticky, and shrinks the cavity.
Ttk_AnchorBox places a box with the requested width and height inside the parcel according to the
specified anchor option.
Ttk_BoxContains tests if the specified x, y coordinate lies within the rectangular region box.
PADDDING
The Ttk_Padding structure is used to represent borders, internal padding, and external margins: typedef
struct {
short left;
short top;
short right;
short bottom; } Ttk_Padding;
Ttk_MakePadding is a convenience routine that contsructs a Ttk_Padding structure with the specified left,
top, right, and bottom components.
Ttk_UniformPadding constructs a Ttk_Padding structure with all components equal to the specified border.
Ttk_AddPadding adds two Ttk_Paddings together and returns a combined padding containing the sum of the
individual padding components.
Ttk_RelievePadding adds an extra 2 pixels of padding to padding according to the specified relief. If
relief is TK_RELIEF_SUNKEN, adds two pixels at the top and left so the inner region is shifted down and
to the left. If it is TK_RELIEF_RAISED, adds two pixels at the bottom and right so the inner region is
shifted up and to the right. Otherwise, adds 1 pixel on all sides. This is typically used in element
geometry procedures to simulate a "pressed-in" look for pushbuttons.
CONVERSION ROUTINES
Ttk_GetPaddingFromObj converts the string in objPtr to a Ttk_Padding structure. The string
representation is a list of up to four length specifications "left top right bottom". If fewer than four
elements are specified, bottom defaults to top, right defaults to left, and top defaults to left. See
Tk_GetPixelsFromObj(.TH 3tcl) for the syntax of length specifications.
Ttk_GetBorderFromObj is the same as Ttk_GetPaddingFromObj except that the lengths are specified as
integers (i.e., resolution-dependant values like .TH 3tclm are not allowed).
Ttk_GetStickyFromObj converts the string in objPtr to a sticky bitmask. The string contains zero or more
of the characters n, s, e, or w.
